Sill Blair—Herman (TK), STP -75-3(107), CN 21704 Floodplain Certification (Bridge -Sized
Structures)
The Blair - Herman project is 9.84 miles in length and located on US -75 in Washington County, starting
0.31 miles south of the northern corporate limits of Blair at mile marker (MM) 116.35, and extending
north to MM 126.19, 0.29 miles north of the northern corporate limits of Herman. The improvements on
this project consist of milling and resurfacing the roadway and surfaced shoulders with asphalt, bridge
repairs, bridge replacements and removing and replacing guardrail. There will be no grade raise as a
result of the mill and overlay operation. However, the project will result in a grade raise along the
highway at curve locations where superelevation will be corrected and locations where the roadway
centerline elevations increase due to template correction.
Embankment work will be limited to locations where superelevation/template correction is required,
at locations where guardrail is being replaced to meet current standards, and at locations where
bridges will be replaced.
This floodplain certification memorandum only addresses project work for bridge -sized structures and
their conveyed floodplains with an accompanying memorandum which addresses the remainder of work
on the project.
The following Zone A Floodplains are conveyed through bridge -sized structures:
North Creek, City of Blair, Section 27 T19N R11E (SIM 11877)
The base flood (100 -year event) is currently conveyed by a twin 12 foot by 12 foot. The culvert is use in
place and extend as needed for this project. The project does not affect the conveyance of the flow
through the culvert or change the elevation of the highway, and therefore will not cause the base flood
elevation to increase. This falls within the Zone A floodplain regulations for changes in a floodplain.
Stuart Creek, Washington County, Section 27 T1 9N R11 E (S075 11925)
The base flood (100 -year event) of 4,400 cubic feet per second is currently conveyed by a 100 foot
concrete girder bridge at a base flood elevation of 1051.9 feet and does not overtop the highway at this
location. The base flood elevation was determined as part of an NDOT study for the design of the bridge
completed in 2007. Bridge work will consist of deck repairs, a three inch asphalt overlay, replacement of
expansion joints, and a remodeled buttress. This work will result in a three (3) inch grade raise at the
bridge site. The work will not cause the base flood elevation to increase. This falls within the Zone A
floodplain regulations for changes in a floodplain.

January 28, 2020
New York Creek, Village of Herman, Section 32 T20N R11 E (S075 12479)
The base flood (100 -year event) is currently conveyed by a 150 foot long steel girder bridge at an
elevation of 1042.9 feet and does not overtop the highway. The base flood elevation was determined as
part of an NDOT study for the replacement of the bridge on this project. The project will replace the bridge
with a 160 foot long concrete girder bridge. This work will result in a maximum of a 1.1 foot grade raise
from the existing bridge centerline profile due to curve super elevation corrections and will have a lowered
existing low structure to 1044.78 feet. The grade raise transitions to existing grade conditions within 400
feet either side of the bridge. The new low structure elevation is maintained above the analyzed base
flood elevation and will not impact the overall conveyance in the floodplain from the existing conditions.
Also, the grade raise extents at the bridge are maintained above the analyzed base flood elevation and
will not impact conveyance in the floodplain. The work will not cause the base flood elevation to increase.
This falls within the Zone A floodplain regulations for changes in a floodplain.
New York Creek Tributary, Village of Herman, Section 29130 T20N R11E (S075 12533)
The base flood (100 -year event) is currently conveyed by a 42 foot long concrete slab bridge at an
elevation of 1039.5 feet and overtops the highway. The base flood elevation was determined as part of
an NDOT study for the replacement of the bridge on this project. The project will replace the bridge with
a 50 foot long concrete slab bridge. This work will result in a maximum of a 0.77 foot grade raise from
the existing bridge centerline profile. The grade raise transitions to existing grade conditions within 400
feet either side of the bridge. The low road elevation at the site of 1034.69 feet will be maintained. While
there is a grade raise at the site within the extents of roadway overtopping, the overall floodplain
conveyance is maintained due to a longer proposed bridge with more conveyance than the existing
bridge. The work will not cause the base flood elevation to increase. This falls within the Zone A floodplain
regulations for changes in a floodplain.
The following structures are not located in mapped floodplains, and therefore do not require floodplain
permits: S075 12252

SUBJECT Blair - Herman, STP -75-3(107), CN 21704
Floodplain Certification
The Blair - Herman project is 9.84 miles in length and located on US -75 in Washington County,
starting 0.31 miles south of the northern corporate limits of Blair at mile marker (MM) 116.35, and
extending north to MM 126.19, 0.29 miles north of the northern corporate limits of Herman. The
improvements on this project consist of milling and resurfacing the roadway and surfaced
shoulders with asphalt, bridge repairs, bridge replacements and removing and replacing guardrail.
There will be no grade raise as a result of the mill and overlay operation. However, the project will
result in a grade raise along the highway at curve locations where superelevation will be corrected
and locations where the roadway centerline elevations increase due to template correction.
Embankment work will be limited to locations where superelevation/template correction is required,
at locations where guardrail is being replaced to meet current standards, and at locations where
bridges will be replaced.
Please review the attached mapping showing where this project encroaches into flood zones. This
project has parallel and perpendicular encroachments within Zone A Floodplains at the following
locations:
South Creek Crossing at MM 117.42, City of Blair, Washington County, Section 3, T18N,
R11 E
This project crosses the Zone A Floodplain at a twin 8 -foot span, 10 -foot rise concrete box culvert,
200 feet in length. This crossing is located within a horizontal curve where the superelevation at
the highway will be corrected and guardrail will be replaced. A hydrologic and hydraulic analysis of
this floodplain crossing of the highway was completed for this certification. The base flood (100 -
year storm event) of 4000 cubic feet per second (cfs) is conveyed by the culvert at an elevation of
1071.18 which overtops the highway. The proposed work at this location will result in a grade raise
of 0.68 feet. The existing culvert is to be used in place and will not be extended. The impact of this
work will increase the base flood elevation to 1071.69, a 0.51 foot increase. This falls within the
Zone A Floodplain regulation's allowance of up to a 1 -foot cumulative increase in the 100 -year
Base Flood Elevations for changes in a floodplain.
North Creek Crossing at MM 118.77, City of Blair, Washington County, Section 27, T19N,
R11E (Structure No. S075 11877)
This project crosses the Zone A Floodplain of North Creek at a Twin 12' x 12' Concrete Box
Culvert, 128 feet in length. The existing culvert will be used in place with no extensions or
modifications. The roadway work at this location is limited to milling and overlay with no grade
raise. This bridge -sized structure is certified by the NDOT Bridge Division's Hydraulics Section in
an accompanying memo.

Stuart Creek Crossing at MM 119.25, Washington County, Section 27, T19N, R11E (Structure
No. S075 11925)
This project crosses the Zone A Floodplain of Stuart Creek at a single span steel girder bridge, 102
feet in length. Bridge repair and overlay will be performed on this structure as part of this project.
As a result of the overlay on the bridge, there will be a 3 inch grade raise. This bridge structure is
certified by the NDOT Bridge Division's Hydraulics Section in an accompanying memo.
Lippincott Creek Crossing No. 1 at MM 120.09, Washington County, Section 21, T19N, R11E
This project crosses the Zone A Floodplain at a 54 -inch CMP, 84 feet in length. The existing culvert
will be used in place with no extensions or modifications. The roadway work at this location is
limited to milling and overlay with no grade raise. The existing driveway located just south of the
culvert will be milled and overlaid with no grade raise. The proposed work on this project will have
no impact to the base flood elevations and therefore complies with the Zone A Floodplain
regulation's allowance of up to a 1 -foot cumulative increase in the 100 -year Base Flood Elevations.
Lippincott Creek Crossing No. 2 at MM 120.19, Washington County, Section 21, T19N, R11E
This project crosses the Zone A Floodplain at a 14 -foot span, 14 -foot rise concrete box culvert, 132
feet in length. The existing culvert will be used in place with no extensions or modifications. The
roadway work at this location is limited to milling and overlay with no grade raise. The proposed
work on this project will have no impact to the base flood elevations and therefore complies with
the Zone A Floodplain regulation's allowance of up to a 1 -foot cumulative increase in the 100 -year
Base Flood Elevations.
New York Creek Crossing No. 1 at MM 124.79, Village of Herman, Washington County,
Section 32, T20N, R11 E (Structure No. S075 12479)
This project crosses the Zone A Floodplain of New York Creek at a 4 -span steel girder bridge, 151
feet in length. This bridge will be replaced as part of the project. The new bridge will be overlaid
resulting in an additional 3 -inch grade raise. This bridge structure is certified by the NDOT Bridge
Division's Hydraulics Section in an accompanying memo.
New York Creek Crossing No. 2, MM 124.79 to MM 125.19, Village of Herman, Washington
County, Section 32, T20N, R11E
This project crosses the Zone A Floodplain of New York Creek along this segment of US -75. The
following culverts are present along this segment:
• 4' x 4' Concrete Box Culvert, 89 feet in length, located at MM 125.16, Station 741+58
• 30" CMP, 102' feet in length, located at MM 125.18, Station 742+84
The existing culverts will be used in place with no extensions or modifications. The roadway and
intersection work along this segment are limited to milling and overlay with no grade raise. The
resurfacing work will not impact flood flows during a 100 -year event. The proposed roadway work
along this segment of the project will have no impact to the base flood elevations and therefore
complies with the Zone A Floodplain regulation's allowance of up to a 1 -foot cumulative increase in
the 100 -year Base Flood Elevations. Certifications have been provided for the two culvert locations
shown above.

County, Section 29, T20N, R11E
Highway US -75 parallels the Herman Creek floodplain along this segment. The existing culverts
will be used in place with no extensions or modifications, and the roadway and intersection work
along this segment are limited to milling and overlay with no grade raise. The resurfacing work will
not impact flood flows during a 100 -year event. The proposed roadway work along this segment of
the project will have no impact to the base flood elevations and therefore complies with the Zone A
Floodplain regulation's allowance of up to a 1 -foot cumulative increase in the 100 -year Base Flood
Elevations.
Herman Creek Crossing at MM 125.33, Village of Herman, Washington County, Section 29,
T20N, R11 E (Structure No. S075 12533)
This project crosses the Zone A Floodplain of Herman Creek at a 3 -span concrete slab bridge, 42
feet in length. This bridge will be replaced as part of the project. The new bridge will be overlaid
resulting in an additional 3 inch grade raise. This bridge structure is certified by the NDOT Bridge
Division's Hydraulics Section in an accompanying memo.
